I was not looking for a pissing match to ensue... so this will be my last post as disrespectful comments do not work well for me.
Everyone has and opinion, I can only contribute what seems works for my animals; that I can stand by... my dogs, cat, paraket, pigs, lambs, goat, chickens, geese...

We did lots of research into DE... and it is controlling our flea population on our animals... we do not dust them, it is in their food..... the Co-op feed store also mixes it in their various feeds and swear by it. Like anything else, you'll get...
cat, dogs, pigs, lambs, goat... they all get it in their food, about a tsp for cat, tbsp each of the dogs and a great big shot for the hooved critters ! It gets sprinkled on their bedding in their huts including the geese/turkey hut, coop and meatie huts.
Flea season is generally on right now...
